T 0 all whom it may concern:

Be it known that we, WILLIAM P. BARTEL and SYDNEY E. TAFT, residing at,respectively, l/Valtham and South Framingham, both in the county ofMiddlesex and State of Massachusetts, have invented new and usefulImprovements in Hook-Separating Mechanism, of which the following is aspecification.

This invention relates to devices for separating lacing hooks and thelike from a 4 quantity 'of the same contained in a hopper and feedingthe lacing hooks or like articles thus se arated to a raceway, downwhich they slide, said lacing hooks being subsequentlyfed one byone bysuitable mechanism, to be driven and clenched by other suitablemechanism in sheet material, such as the uppers of bootsand shoes.

The device for separating the lacing hooks,

. as hercinbefore set forth, consists of a rotary picker-plate, wellknown to those skilled in the art, to which an intermittent rotary-mo- Ition is imparted whereby the lacing hooks are picked up upon thedifferent blades of the picker plate during the rotary motion of saidpicker. plate and while the picker-plate is stationary these lacinghooks slide off the blades of the icker-plate onto the raceway. Indevices of din I picker-plate in its forward motion between its throughthe middle part of its movements in? crease its speed, and finally cometo astop slowly. In other words, said picker-plate has an intermittentdifferential rotary movement imparted thereto and in order that theconsecutive movements of the picker plate may be separated one from theother by as slight a sirable t at the mechanism which feeds saidpicker-plate shall not only be capable of imparting the slowdifferential forward rotary movement, hereinbefore set forth, to saidplate, but that in its return movement said" ckly. Indevices of thecharacter. hereinbefore set forth, it is also. desirable that when theraceway has been filled with hooks, the mechanism for feeding the hooksfrom the or to, the raceway, viz., the picker-plate in t s instance,should be stopped while the machine to which it is attached containingthe driving and setting mechanisms shoul 4 mechanism shall be moved veryqui hop .easi y 0 quickly 's class it is desirable that the periods ofrest'should start slowly, then eriod of time -as possible, it is de-.

' Fig. 2is a sectiom-part continue its operation. Otherwise, when theraceway becomes filled the lacing hooks will be carried around by thepicker-plate and emptied into the hopper again as the;

blades escend during their rotary motion and the continual movement'ofthe pickerplate through the lacing hooks at the bottom of the hoppertends to injure the lacing hooks and remove more'or less japan from thesurface thereof. It is, therefore, desirable that the picker-plate shallonly be rotatedsufficiently to kee the raceway well supplied with lacinghoo s The object ofthis invention, therefore,'is to -rovide a cheap,simple, durable and eratcd mechanism which will imparta s to thepicker-plate'and without moving said pickerp and, further, the object ofthisinventlon is to provide a mechanism for driving said picker-plateoperating -mechanis'm which may be readily disconnected therefrom, thuswhich will return In chanism stationary when the raceway is filed-withhooks, as hereinbefore described.

ow intermittent rotary movement I leaving said picker-plate and itsdriving The invention consists in the'combination.

and arrangement of parts set forth in the following specification and.particularly pointed out in the claims thereof.

In the drawings I have illustratd my improved lacing hook separating'andfeeding mechanism as attached to the: frame of a lacing hook settingmachine and driven by a pulley loosely mounted upon the. main driv' mgshaft of said lacing hook setting machine. Referring to the drawings:Figure 1 is a of my improved mechanismfor plan view separating andfeeding lacing hooks and the like, together with a, portion of the frameof a lacing hook setting machine upon which said separating and feedingmechanism is supported, the main driving shaft of said lacing hook'setting machine-and driving pulley therefor, said driving shaft beingroken away to save s ace in the drawings. y in elevation, taken on line2 '2 of Fig. 3, looking toward the right in said figure. tion of theparts illustrated-in Fig. 1, the frame of -the lacijng hook'settingmachine being broken away to save spacein the a detail front elevationdrawings. Fig. 41s of the hopper and raceway, the picker-plate Fig 3 isa side elevabeing indicated by dotted'lin'e's and the raceway and hopperbeing broken away to save space in the drawings. 7 Like numerals referto like parts throughout the several views of the drawings.

In the drawings, 6 is a "hopper of well known construction, which isfastened to the frame ,7 of alacing hook setting .machine,

, Afrotary picker-plate 8 is arranged to rotate L5 Within an annularrecess' 10 provided in said hopper adjacent to the cover 6 thereof andis constructed with-a plurality 'of radial arms .8, 8. A shaft 9 isjournaled to rotate in a bearing 11 in said hopper and has rigldly 8 andat the opposite end thereoffrom that to which said picker-plate isattached a ratchet 12 is fastened. A lever 13 is jour naled to rockloosely upon the picker shaft- Said lever 13 20, 9 adjacent totheratchet 12.

has a pawl 14 pivoted thereto which engages the ratchet I2 and isprovided'with a slot 15 extending longitudinally thereof upon the'opposite side of the shaft from that upon tion isjm'p'arted to thelever 13 by a crankarm 16, and crank-pin 17, 'said crank-pin rojectinginto the slot 15 in said lever 13.

he crank-arm 16 is fast to a crank-shaftdS journaled to rotate in abracket 19 fast to the frame 7. A rotary motion is imparted to thecrank-shaft 18 by ,a pulley 20 fast thereto and driven by a belt 21,which, in turn, is driven by a pulley 22 fast to an intermediate 5 shaft23 (Figs. 2 and 3). The intermediate shaft 23 is journaled to rotate ina bearing provided in the interior of the gear 24 and its hub x The gear24 is locked, when desired, to the intermediate shaft 23 by a frictionclutch 26, consisting of two members, one of said members being a disk27 provided upon its periphery with a conical friction surface 28 whichengages a conical friction surface 29 provided upon the interior of thegear'24.

A spiral spring 30 bears at one end thereof against the hub of thepulley 22 and at the other end thereof against a shoulder 31 formed uponthe interior of the gear 24. Thehub 25 has provided at the left hand endthereof (Fig. 2) an annular flange 33 which bears against. a bracket 34fast to the frame 7. The'hub 25 of the gear 24 is journaled to rotate ina. bearing 35 provided in said bracket 34. Rotary motion is imparted tothe gear 24 by a gear 36 fast to a pulley 37 journaled to rotate looselyupon themain driving shaft 38 of the lacing hook setting machine, saidmain driving shaft being j our- 0 naled to rotate in a bearing 39 onsaid frame.

frame 7 and has a vertical arm 42 extending upwardlyfrom said pivotadjacent to the left hand face (Fig. 2) of the pulley 22. Said 5 leverhas a horizontal arm-43 by means of attached to one end thereof thepicker plate which said pawl is located. aA rocking mo- A clutch lever40 is pivoted at 41 to the the disk 27, intermediate saft 23 and pulleythe spring 30 with its friction surfaces 28 and =29 in contact one withthe other, but when it seams which it ma be operated,e1ther -by hand,

or, if referred, may be connected with a suitab e ,treadle and operatedby foot power. The friction clutch 26 is normally held by the frame 7(Fig. 3), said dog being rotated upion itspivot out of contact with thearm 43 35 w en it is desired'to rock the lever 40 to release the pulley22 and allow the frictional surfaces of the clutch to be brought intocontact b the spiral spring 30, or into the posi- 'tion illiistrated inFig. 2.

The operation of the mechanism hereinbefore specifically described is asfollows: Assuming the necessary amount of lacing hooksto be placedwithin the hopper 6 and the clutch 26 to be in operative position, as

' illustrated in Fig. 2, the main driving pulley 37 'impartsa rotarymotion to the gear 36 which, in turn rotates the gear 24, thus rotatingthe disk 27, intermediate shaft 23 and pulley 22. The pulley 22 drivesthe belt 21, thus rotating the pulley 20 in the direction of the arrow(Fig. 3). The pulley 20 rotates the crank-shaft 18, crank-arm16 andcrankpin 17 in the direction of the arrow (Fig. 3). As the crank-arm 16and crank-pin 17 are thus rotated in the direction of the arrow (Fig. 3)it will be seen that said crank-pin will travel longitudinally of theslot 15 toward and away from the picker-shaft 9, which con- 7 stitutesthe pivot of the pawl-lever 13, so 1 0 that duringone portion. of therotation of said crank-arm and crank-pin, said crankpin will be nearerthe pivotal center of the pawl-leverthan at another time, and by'reference to Fig. 3 it will be seen that when the crank-pin is farthestremovedfrom the pivotal center of the pawl-lever 13, said lever isbeingmoved in a direction" to rotate the picker-plate throu h the pawl14, ratchet 12 and. shaft 9, and w ensaid craiik-pin is pass: ingthrough that portion of its rotation-which brings it nearest to thepivotal center of the pawl-lever said pawl-lever is being movedbackwardly or in the direction to carry the pawl backwardly from onetooth of the ratchet to engage a new tooth thereon, so

that it will be evident that a slow forward and quick return movement isimparted to the pawl, and further at eachend of the movement of the pawlduring the beginning of its forward movement and during the end of saidforward movement, and also at the beginning of its return movement andthe end of its return movement, said pawl will travel slower than in themiddle of either of said movements, for the reason that at such timesthe crank-arm is in a position similar to that illustrated in Fig. 3, sothat it is traveling longitudinally of the slot 15 without moving thepawl-lever to any more than the slightest extent. In other words, themedian longitudinal line of said slot is tangent at such times to acircle described by p the center of the crank-pin 17.

As the picker-plate is rotated, as hereinbefore described, lacing hooksare carried by the arms 8, 8 of said picker-plate in the.

bottom of the hopper upwardly and slide along the upper surface of saidarms, said lacing hooks passing outwardly through a suitable orifice inthe sideof the hopper onto the raceway 46 and slide downwardly upon saidraceway to the driving and setting mechanism in a manner well known tothose skilled in this art. When the raceway becomes filled the operatorrocks the clutch leverat) upon its pivot to disconnect the members ofthe clutch 26, as hereinbefore described, thus disconnecting themechanism which drives the pulley-operating me'ch anism therefrom andstopping the rotation of the picker-plate.

Having thus described my invention, what I claim and desire by LettersPatent to secure is:

In a device of the character described, a hopper, a picker platejournaled to rotate within said hopper, mechanism adapted to impart anintermittent rotary motion to said picker plate, said mechanism adaptedto im part a slow forward motion to said picker plate and to returnpreparatory to imparting another forward movement to said picker plateat a relatively rapid; rate of speed,
